English designation (centrifugal cone column) for a physical process used in the distillation and rectification (separation of liquid mixtures) is used. The rotating cone plate in conjunction with a vacuum distributes the liquid to be separated very thinly by using the centrifugal force. That at the beer production Processes that have been in use for some time now also apply to the winemaking Application. It is used for the production of dealcoholized or low-alcohol wine alcohol reduction. concentrated grape must and RTK, for the optimization of the Aromas or the sensory Properties, as well as for the reduction of too high a content of sulphurous acid used.
The wine is broken down into fractions. Fraction is a group of substances with the same or similar boiling point. That can be water alcohol and be different flavor groups. The wine (or liquid) is heated under vacuum, which allows relatively low temperatures. Different boiling points of the individual fractions can separate them (at different times). Then individual fractions are added again and any undesired ones are left out, which results in a different taste alcohol content and flavorings respectively. relative density results. For example, a common use in Australia is “optimal gradation” due to alcohol withdrawal ( Sweet spot ) to reach.
Compared to conventional processes such as the distillation From schnapps, much smaller portions of the starting product are evaporated. The aroma or taste is preserved, which would be changed or lost at high temperatures. Usually only a part of the wine is treated in this way and mixed with the rest after adding the extracted substances. The end product could be exaggerated as “ Cuvée of himself ”. The question is whether you can use it to produce a wine with the desired aroma image regardless of the vintage influence in "the same quality". Such wines are called derogatory rather "column wines" or Coca-Cola wines,
The removal of wine faults targeted elimination of the causative substances is rather not possible. Because by spinning cone column aroma groups (substance groups), but not individual aromas (there are many hundreds in wine) can be fractionated. The procedure, which is not uncontroversial, came into discussion through the US-EU wine trade agreement signed in 2005. The application is severely restricted for the EU countries (e.g. allowed for one alcohol reduction ), Wines treated in this way from the USA may be marketed in the EU. The similar process electrodialysis however, is allowed in the EU.
The process is clearly shown in a video (click to view) by the Californian manufacturer ConeTech .
